S. Geological Survey (USGS), Department of the Interior, under USGS Award Number 05HQGR0026. The views and conclusions contained in this document are those of the authors and should not be interpreted as necessarily representing the official policies, either expressed or implied of the U.S. Government. PREFACE The Yellowstone-Jackson Hole-Star Valley corridor is located within the seismically and tectonically active Intermountain Seismic Belt in westernmost Wyoming and eastern Idaho. The corridor has the highest seismic hazard in the Intermountain U.S. based on the U.S. Geological Survey’s National Hazard Maps. The region contains the heavily visited Yellowstone and Teton National Parks and the rapidly growing areas of Jackson Hole and Star Valley. Although there has only been one large earthquake in this region in historical times (1959 moment magnitude [M] 7.5 Hebgen Lake), abundant geologic evidence exists for the past occurrence of surface-faulting earthquakes of M 7 or greater. -

Pierce and Colman: Submerged Shorelines of Jackson Lake, Wyoming: Do They Exist and SUBMERGED SHORELINES OF JACKSON LAKE, WYOMING: DO THEY EXIST AND DEFINE POSTGLACIAL DEFORMATION ON THE TETON FAULT Kenneth L. Pierce u.s. Geolo:.:Jical. Survey Denver, co Steven M. Colman u.s. Geological Survey Woods Hole, M A Obj::ctives The Teton fault is one of the moot active normal faults in the world, as attested by the precipitous high front of the Teton Range. After deglaciation of northern Jackson Hole arout 15,000 years ago (Parter and others, 1983), offset on the Teton fault eouthwest of Jackoon Lake has tntaled 19-24 m (60-80 feet) (Gilbert and others, 1983). In less than the last 9 million years, offset on the Teton fault has tntaled from 7,500 to 9,000 meters (Love and Reed, 1971). Figure 1 shows how downdropping on the Teton fault results in tilting of Jacks::>n HoJe towards the fault. Submerged paJ.eoohorel:ines of Jackoon Lake may record this downdropping and tilt because the level of Jackoon Lake is controlled by both the furtui.tous ,{X)Sition of the Jake ootlet and the immediate downstream course of the Snake River (Figure 1). The ootlet of Jackson Lake is 12 km east of the fault and from there the Snake River has a very low gradient to a bedrock threshold 6 km further east. Thus the level of Jackson Lake is controlled by the bed of the river east of the hinge line of tiJ.ting (Figure 1). The postglacial history of movement on the Teton fault may thus be recorded by paJ.eoohorelines submerged OOJ.ow the level of the pre-dam Jake. -

National Park Service Cooperative Agreement # H1200040001 HYDROLOGY AND GEOMORPHOLOGY OF THE SNAKE RIVER IN GRAND TETON NATIONAL PARK, WYOMING FINAL REPORT by Nicholas C. Nelson and John C. Schmidt Department of Watershed Sciences Utah State University Logan, Utah 2007 ABSTRACT Hydrology and Geomorphology of the Snake River, Grand Teton National Park, Wyoming The influence of significant tributaries that join the Snake River within 10 km of Jackson Lake Dam (JLD) mitigate some impacts resulting from nearly 100 years of flow regulation in Grand Teton National Park. I analyzed measured and estimated unregulated flow data for all segments of the study area by accounting for tributary flows. The magnitude of the 2-yr recurrence flood immediately downstream from JLD decreased 45% since 1958 relative to estimated unregulated flows, whereas that downstream from Buffalo Fork, the largest tributary, decreased 36%. There has been no long-term progressive geomorphic change on the Snake River resulting from dam regulation. I mapped the bankfull channel on four series of aerial photographs taken in 1945, 1969, 1990/1991, and 2002 and analyzed channel change in a geographic information system. Periods of low-magnitude floods (1945 to 1969) resulted in widespread deposition whereas periods of high-magnitude floods (1969 to 1990/1991 and 1990/1991 to 2002) resulted in widespread erosion; channels narrowed and widened by as much as 31%. I mapped three distinct deposits within the Holocene alluvial valley. The lower floodplain covers 3.5% of the mapped area in the form of abandoned channel and inset, channel-margin facies and has inundating recurrence intervals of one to two years. -

Grand Teton National Park Photoguide
Grand Teton National Park Photoguide by Miles Hecker Go to Teton Photo Map Table of Contents Fortress of Solitude © Miles Hecker Preparation Photographic Ethics Clothing and Personal Items Equipment Lodging and Camping Dining and Food Grand Teton National Park Photomap All materials © 2010 WyoFOTO LLC Preparation Physical Preparation Photographic sites numbered 1 through 23 on the Teton Photo map are located within a 100 yard or less easy walk from the spot where you can park your vehicle. The majority of these sites, are 100 feet or less from parking. As such, no special physical preparation is needed to photograph these areas. Sites 24, 25 and 26 are located many miles from the nearest parking area. Photographing them requires either a multiday backpacking trip or a very long and strenuous day hike at high altitude. Only you know if you are physically able and equipped to deal with such an adventure. If in doubt, proceed with caution. Teton rescues are very involved and costly. If the NPS determines the hiker was at fault, it will bill the hiker for the rescue operation! Mental Preparation The Tetons are part of the Greater Yellowstone Ecosystem. As such, they do not have a convenience store or restroom located at every photographic location or stopping area. If you are not prepared to deal with these inconveniences, you have come to the wrong region of our beautiful country. As wild as this area is in theory, June, July and August are a zoo in this great national park. Some 2 to 3 million tourists pass through during this period. -

National Park Service Yellowstone Fall U.S. Department of the Interior Welcome to your Yellowstone adventure. Yellowstone is a special place, and very different from your home. Like any grand adventure, your Yellowstone journey will take you to impressive new locations and introduce you to new expe- riences. That means there are different risks here than you may have faced before. You are responsible for your own safety. We need your help to preserve the wildlife, natural features, and cultural treasures that bring so many visitors to Yellowstone. The park rules protect you and also protect the park. Follow the park rules for a safe and enjoyable visit. Please be a positive part of the Yellowstone experience. Road Safety Wildlife Safety Safety in Bear Habitat Traffic-related accidents are the most common • Animals in Yellowstone are wild and dangerous. • All of Yellowstone is bear habitat. cause of injury and death in the park. • Stay 100 yards (91 m) away from bears and • Carry bear spray and know how to use it. • Drive cautiously. The park speed limit is 45 mph wolves. • Hike in groups of three or more people. (73 kph), except where posted slower. • Stay 25 yards (23 m) away from all other animals. • Make noise to avoid surprise encounters. • Watch out for wildlife on or near roadways. If the animal moves closer—you must back away. • Never run from a bear, they instinctively chase • Use pullouts. If you need to stop for any reason, • Bison, bears, and elk have injured and killed running prey. use a road pullout and let faster traffic pass. -
